Abstract
The effect of doping with Ag of the bulk superconducting Hg0.3La0.7Ba2Ca3(Cu1 − xAgx)4O10 + δ, 0.1 ≤ x ≤ 0.3 phase (Hg-1234) is presented. The lattice parameter a = 3.824 A remains constant, while parameter c was found to increase from c = 19.0225 A (x = 0.0) to 19.08 A (x = 0.3) with the addition of Ag. The variation of Tc versus the c-parameter exhibits a cupola-shaped behavior. The irreversibility line is thermally activated. The logarithmic plot of Hirr versus (1 − Tirr/Tc(0)) shows a crossover temperature reflecting a transition from two- to three-dimensional behavior with increasing temperature. Fitting of the results to different models is discussed. Thermally activated de-pinning according to Matsushita's formula gives the best fit.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
